Is there even a kit for the VANOS seals?
BTW, in putting my head back together on of the studs on intake cam was screwed so I tried ordering a new one. My VANOS system has been superceded by the newer version with the spring plate so I had to order all of that stuff to go with the new studs.
Is the newer version of VANOS a noticeable improvement over the original one? Is it quieter?

While I'm waiting for parts I've got mine laying around. Here is what it looks like broken apart... very simple.
It's a bi-stable hydraulic device. The solenoid controls pressure to one side of the disk or the other. Doesn't really matter how tight the seal is, excess oil leaks into the head.
What exactly does Dr. Vanos do?

Dr Vanos Rebuilds vanos units.
The biggest way I could see improving the VANOS unit would be to change the way the shaft fits through the cover. It's a loose fit and I can see how it could rattle. Put a stainless sleave in the cover and then an O ring to keep the shaft from rattling.
I could see that.
